What is a potential drawback of implementing a queue using an array with a fixed size?
Risk of queue overflow if the queue reaches its maximum capacity.
Increased time complexity for enqueue and dequeue operations.
Requirement of complex algorithms for insertion and deletion.
Inability to store elements of different data types.
In a circular queue implemented using an array of size 5, the front is at index 3, and the rear is at index 1. What happens after two dequeue operations?
The front moves to index 0, and the rear remains at index 1.
The front moves to index 0, and the rear moves to index 4.
The front moves to index 1, and the rear moves to index 4.
The queue becomes empty.
Which of the following real-world scenarios can be effectively modeled using a queue?
Managing a priority-based task list.
Implementing an undo/redo functionality in a text editor.
Handling customer service requests in a first-come, first-served manner.
Storing the browsing history in a web browser.
What is the primary characteristic that distinguishes a queue from other linear data structures?
It allows for random access of elements.
It is a sorted data structure.
Elements are added at one end and removed from the other.
Elements are added and removed from the same end.
If a queue is implemented using a fixed-size array, what condition leads to a 'queue overflow' situation?
Trying to access an element beyond the queue's capacity.
Trying to sort the elements in the queue.
Trying to remove an element from an empty queue.
Trying to add an element to a full queue.
What is the main advantage of using a circular array for implementing a queue compared to a regular array?
Better handling of sorted data
Reduced memory consumption
Efficient utilization of space after multiple enqueue and dequeue operations
Faster access to individual elements
What is the primary difference between a queue and a stack?
Queues use FIFO (First-In-First-Out), while stacks use LIFO (Last-In-First-Out).
Queues use LIFO (Last-In-First-Out), while stacks use FIFO (First-In-First-Out).
Queues are linear data structures, while stacks are non-linear.
Queues store numbers, while stacks store characters.
Imagine a print queue in a busy office environment. Which data structure, implemented using an array, would be most suitable for managing this print queue effectively?
Stack
Circular Queue
Hash Table
Binary Tree
How do you efficiently handle the situation where the array representing the queue becomes full?
Delete the oldest element.
Stop accepting new elements.
Use a linked list instead of an array.
Resize the array to accommodate more elements.
What is the maximum number of elements a circular queue of size 'n' can hold?
n - 1
n
It depends on the implementation
n + 1
